Mayweather: “Mixed martial arts is for beer drinkers. Boxing is for everybody. You can’t take my shoes off, take my shirt off and just throw me in a cage. You do that with animals. You can’t do that with me. You don’t do that to humans.”

McGregor: “It’s all I think about. I don’t even sleep that much it’s got that bad. I think you have to have that obsession to get to a high level. That separates those who stay at the middle level and those who go right to the top.”

Winner: Mayweather

Round three

Mayweather: “You know me. I’m running my mouth a lot, and I’m looking for a guy to shut me up. If you don’t shut me up, I’m going to keep running my mouth. Nobody can beat me. There is no way to beat me.”

McGregor: “I see fighters make funny videos about me and stick them on Facebook and get 20 likes. When I make a video, I sell it and make seven figures. That’s the difference.”

Winner: McGregor

Round four

Mayweather: “I’m the best at talking trash. I’m also the best at going out there and backing it up. I’m going to beat you until you respect me. I’m going to beat you and I’m going to make you call me pretty.”

McGregor: “There’s no talent here. This is hard work. This is obsession. Talent does not exist. We are all equals as human beings. You could be anyone if you put in the time. You will reach the top, and that’s it. I am not talented. I am obsessed.”

Winner: McGregor

Round five

Mayweather: “The kid that’s going to beat Floyd Mayweather hasn’t been born yet. Yes, he may, he may have been born – it may be one of my sons.”

McGregor: “Four years ago I fought in London at The Forum in front of about 500 people. Now here I am about to quadruple my net worth with one half a fight. Sign me up. No one is going to kick, knee or elbow.”

Winner: Mayweather

Round six

Mayweather: “You’ve got to have a villain, and they’ll always make me a villain. I’m used to it – it makes me work harder, and it makes me fight harder.”

McGregor: “I don’t feel pressure in a negative way. I like pressure. I feel excitement and calm at the same time. No pressure, no diamonds. I want pressure: pressure creates drama, creates emotion.”
